Micro-enterprise in one week

I would choose option A.

I like projects with hard/quick deadlines. Helps to stay focused and ship something by the end. Little time to overthink. And remember you can always tweak and make better after launch.

A time limit like this is an awesome way to ensure you build something useful! The constraint will likely help you accomplish more shipped product in a week than you could in much more time.

I've done very rapid launches of my own and helped a couple of clients go from zero to launch in a week. You can absolutely get revenue this week. Based on my experiences, a few thoughts:

• Realize that what you ship by EOW may be a much lower quality of work than you're used to. "Quality" here doesn't mean it doesn't work, it means it won't have all the bells and whistles. What gets cut is obviously project-specific; in this case, design might rate higher than some features. With a week as your timeline, you will likely only have time to do the very basic of everything. Cut everything you can.
• Break tasks down to a fixed number of hours. Treat each task as a test: pencils down at the end of the allotted time. No excuses.
• It's fine to leave room for manual processes. For example, fulfillment can be 100% manual to start.
• Don't underestimate the amount of work required to launch. Building the product is just one item out of many you will need to launch.
• Seriously, cut more from your plan. Make a "Week 2" bucket in your Trello/Basecamp/etc. and move the cut stuff there.
• It's worth it to develop a buyer persona and reason they will buy at the very beginning. This will drive a lot of decisions as you move through the week.
• The 7-Day Startup is a quick read and lays out a plan for doing exactly this. You don't have time to read it this week, but you could look at the section headers to develop an attack plan.
• Use every shortcut. Design templates, all the OSS you can. Buy pieces if you are able and it would help. Once you prove that you can generate revenue, you can fix all this.
• Cut more from your plan, you can add it next week.

Of your options, I would be most prone to C. I'm not into stickers, and photo books mostly sit on the shelf. It might be interesting if I could pay more for larger-format photos delivered as really high-quality posters (even better if you frame it).

Good luck!
